Jammer (hamstring) and Gates (foot) were listed as doubtful on Friday's injury report after not practicing all week.
Mathews (foot) was listed as probable while Jackson (abdomen) and Floyd (groin) were listed as questionable Friday after all three took part in full practice. It was Jackson and Floyd's first practice of the week, while Mathews took part in limited drills on Wednesday.
"The hardest thing about making decisions about guys (playing or not) on Sunday is if a guy is up and going to play, he's got to play," Turner told the newspaper. "If a guy can only play 10 to 15 plays, you have to have a plan for when he can't play anymore. ... It's about getting into a rhythm offensively when it's always changing in terms of the personnel. It makes it a little harder on everyone."
Meanwhile, defensive end Corey Liuget (ankle) is considered probable after practicing full for the second day in a row.
